Working with Entrust Digital Signing Certificates on Linux Ubuntu

The engineering licensing body where I am requires us to use that uses Entrust certificates and services. Notarius has apps for signing/certifying documents, like pdf, with apps running on Windows. For non-engineering applications I’ve been signing/certifying documents using MasterPDF, LibreOffice & other programs on Ubuntu 20.04 with Seahorse as a certificate manager. I’ve requested from Notarius customer support to have the certificates so I can work without their Windows software but they don’t seem to understand the question, insisting I need an epf file, a Microsoft security file. I’m a bit of a cybersecurity newby and I’m wondering exactly what files I should be asking for. For Entrust would it be a .pem, .pki or .crt file? There’s information on how to setup a root certificate for Entrust on Ubuntu but what else do I need? Thanks for any help in this regards.

Best Regards,

I am not rally familiar with, but in most cases a .pem certificate should be sufficient.

However if this does not work, my advise would be to ask your case to be escalated with as they are the provider of the service and they should be able to confirm this.
